Orbit menu now shows assigned roles to antaghud users

[Contrabang]

What Does This PR Do

Orbit menu now shows assigned roles to antaghud users. This means you get a tooltip when you hover over someone to see what their assigned role is, with a little icon. It also lets you search by assigned role, so you can see how many of a specific role there is, such as security officers.

Right now, its currently locked behind antaghud, but it could easily be moved to all observers.

Why It's Good For The Game

QOL for observers, so that you don't need to cross reference with the crew manifest.
